2 Claims.

This invention relates to ventilator screens; and more particularly, one that may serve either as a rain shield or an air ventilator, merely by reversing the screen so that in'one case the metal attachment is on the outside acting as a rain shield, and on the inside'as an air ventilator.

In one of the modified forms, the metal attachment may be reversed Without the necessity of removing the screen.

It is customary to have the window open when a screen is used; and it is objectionable during the night or when absent from the house for a short time to leave the Window open for the reason a sudden rain will be blown through the screen damaging the curtains, floors and furniture. By having the rain guard on the outside, ventilation is obtained, and at the same time, the open window is protected. By reversing and inverting the screen, a wind protector is obtained which will prevent drafts and direct the air toward the ceiling. The screen and rain shield are adjustable so as to fit different windows.

The principal object of the invention is to provide a screen unit with an attachment which may be utilized either for a rain shield or draft regulator.

Another object is to provide a screen unit with an attachment in the form of a draft regulator and rain shield, both adjustable, and detachable from each other.

Still another object is to provide an attachment for screens which may be used both as a rain shield and ventilator and which is quickly combined with a standard screen.

Other objects will be disclosed in the specification and claims forming a part of this application.

In the drawings:

Figure 1 is a perspective of the exterior of a window showing the attachment as a rain shield;

Figure 2 is a perspective of the interior of a window showing the attachment as a draft regulator;

Figure 3 is a vertical section taken on the line 3-3 of Figure 1;

Figure 4 is a detailed perspective of a modified form;

Figure 5 is a detailed perspective of the modified form;

Figure 6 is a horizontal section line 6-6 of Figure 4;

Figure '7 is a perspective of a second modified form showing the fold in perspective; and

Figure 8 is a vertical section through a screen with the ventilator in place; and

Figure 9 is a fragmentary horizontal section taken on the through the screen ventilatorand one side of the window frame.

Referring to the drawings, in which similar parts are designated by like numerals:

Numeral 8 designates a window frame'in which is placed an adjustable screen of the usual con-- windows and the problem presented in connection I with the attachment. Numeral I2 designates the attachment, preferably made/of metal or other material which may be either bent, molded, or easily formed into the desired shape.

Attachment I2 in the preferred form illustrated in Figures 1, 2, 3, consists of a front face I3 hav ing halves I 4 and I5 corresponding to halves It] and II of the screen 9, with each'half I4 and I5 slidably mounted on each other, half I4 having turned edges I6 at the top and bottom to slidably receive the half I5, the halves I4 and I 5 each having side members H, the sides I! having flanges I8 at right angles to the sides I1, and tabs I9 adapted to slide under straps 20 on the face of the screen frames 2I The sides I! and front face I3 are flared outwardly from the screen from a line 22' spaced from the upper edges 23 of the two halves I4 and I5.

The top edge 24 of the half I 4 is formed by bending the top edge 24 upon itself, with a turned down lip 25, with the turned-over portion forming a channel 26 to receive the top edge 23 of the half I5. Hangers 21 are secured to the top edge 24 of half I4 and extend down over the rear of channel 26 to receive the top edge of the screen 9, and thus in cooperation with the straps 20 and tabs l9 securely hold the attachment in position on the screen.

In the modified form shown in Figures 4, 5, and 6, the structure is substantially the same, except that instead of the tabs I9 and straps 20 and hangers 21, the flanges I8 are extended to comprise sockets 28 having sides 29 and back members 30 to receive the screen 9. The hangers 21 are eliminated and the top edge 24 is formed by severing the back member 30 adjacent the end to a point along the top edge and folding material upon itself in the manner shown in the preferred form.

As actually used, the attachment I2 will be secured to the screen 9, either as shown in preferred form as illustrated by Figures 1, 2, 3, or as modified in Figures 4, 5, and 6 and placed in the Window. The screen and attachment being adjusted to fit the window frame as is customary.

If it is desired to use the attachment as a rain shield, the attachment will be on the outside, as shown in Figure 1. If it is desired to use the attachment as a ventilator, as illustrated in Figure 2, it is only necessary to invert the screen from the position shown in Figure 1 to that of Figure 2 Qbviously, too, various materials may be used instead of metaLsuch as galvanized iron or tin which can be easily cut and shaped; translucent material of various shades which is moldable can be used; and the same results can be obtained by making the front face of the attachment out of glass and secured in the side members.

If it is desired to use the screen without the attachment, it can be readily removed, as. illl fir trated and described.

In t e .se ond'mod fied f m, as. il ustrated Figures 7 and 8, the tabs 19, straps 12.0 and hangers 2,1 are eliminated, flanges J8. avin sid members 291 without the back. member 3.9, he side members. .29. fitting over the edges of th screen 9 and into the usu l recesses which th window. slides; The top ed e 24 remain he samerwithout .iolding the material back upon self, as illustrated .inFigure 41,. Thus the, second modified .form may be placed oyer the screen, the top edge. 24. being over. the longitudinal edge of the screen and held in position by contact with the. windowv when used as a rain shield with the side flanges 29v extending over the short sides of the screen. and being. held in the. recess of the window frame.

When used as a ventilator, the inside of edge 24, will be placed beneath the bottom. of the screen, the metal. attachment extended on the inside of the window and the side members 29 will extend around the side edges of the screen om. h si e. flan es.

into the recesses of the window frame. Thus it is not necessary to remove the screen in transforming the metal member from a rain shield to a ventilator, nor is it necessary to have any attachments or locking means on the screen member itself. 7

Numerous variations may doubtless be devised by persons skilled in the art without departing from the principles of my invention. I, therefore, desire no limitations to. be imposed on my invention, except such as are indicated in the appended claims.

What I claim is:

1. A combined ventilator and shield comprising front members slidably mounted one on the other, sides extending inwardly from said members and at substantial right angles to said r m members, flan es extending oppositely from said sides and other side pieces extending from said flanges substantially parallel to the first me tioned sides said .fil n es. and pieces 4219122 1 9. 1' 9.
